Heretofore the general practice has been provide a perforated cylindrical sleeve 10, to support such wicks within a perforated the perforations being utilized as means for cylindrical sleeve, which surrounds the outer raising and lowering the wick by a toothed surface of the wick, and which is permawheel (not shown) in a manner well undernently secured to the wick by means of prongs stood by those skilled in the art. The sleeve extending from the bottom of the sleeve and may be transversely split, as at 11, and is bent over to engage the interior of the wick. preferably made of a suitable resilient metal, Generally these metallic sleeves extend upso that the edges 12 and 13 will spring towardly to such an extent that they cover gether, and thereby hold the wick in posimore than half of the outer surface of the tion, when it is placed in the sleeve. c5 wick, and thus, less than half of a wick In order to hold the edges in accurate equipped with a sleeve of this type can be alignment a channel 14 may be struck outused, as the wick and sleeve must be thrown wardly and circumferentially around the away as soon as the wick has burned down body portion a short distance from the edge to the upper edge of the sleeve. 12, as shown in Figs. 1 and 4:.

In place of using the tongue and channel In the drawings, Fig. 1 is a'vertical secdescribed for properly maintaining theadjational view of my improved wick carrying cent edges of the internal wlck carrier or 45 mechanism; Fig. 2 is an elevation of the the external perforated sleeve in accurate wick, showing a carrier secured thereto; Fig. alignment, I may use other constructions, 3 is a section on line 3-3 of Fig. 1; Fig. 4 included within the scope of my lnvention. is a section on line 4-4 of Fig. 1; Fig. 5 is For instance, Figs. 6 and 7 shows the extera section on line 5-5 of Fig. 1; Fig. 6 is nal perforated sleeve 10 provlded with a 50 a side elevation of a modified form of eXtertongue 30 made out of the material of the sleeve and extending across the open area and projecting through a keeper 31 cut and pressed outwardly from metal of the sleeve adjacent the other edge. This makes a very simple construction and retains the edges of the sleeve against either inward or outward movement. I have shown this construction in Figs. 6 and 7 as applied to the external perforated sleeve. It is apparent however, that the same characteristic may be embodied in the wick carrier.

Likewise both on the perforated sleeve and on the wick carrier, I may employ, if desired, interlocking positioning devices, as illustrated in Figs. 8 and 9. In that case, the sleeve (shown as the external sleeve) 10 has a tongue 35 projecting from one edge and acting between a pair of tongues 36 projecting from the other edge. These tongues are made of the metal of the sleeve itself and are offset from the cylindrical surface so as to lie along the face adjacent the opposing edge, while the body of the sleeve remains in cylindrical registration.

It is to be understood that in use, the operation of the device is the same whichever form of carrier and sleeve construction, as above described, is used.

To hold the wick in position, the perforations in the sleeve 10 may be punched in such a manner that very small burrs 24 are left on the inside of the sleeve. These burrs engage the cotton wick and prevent any possibility of slipping. If desired, several of the prongs 18 may be provided with prick punch burrs 23, which are positioned in such a manner that each will fit in a perforation of the sleeve. These burrs are small enough so as not to interfere with the teeth of the raising wheel in the event that the wheels pass over one of the perforations into which a burr is projected.

In order to insert a new wick in the sleeve, it is only necessary to push the wick and the wick carrier secured thereto downwardly into the sleeve until the bottom of the carrier is within the sleeve, as shown in Fig. l, where it will be firmy held in place by reason of the burrs on the sleeve and on the wick carrier. Thereafter, the height of the wick is adjusted by means of the ordinary toothed wheel mechanism.

When the wick has burned down to a point where it can no longer be used, it is pulled upwardly within the sleeve and is held in its new position by the burrs on the wick car rier and sleeve. This operation may be repeated whenever necessary until practically all of the wick has been burned, when the small remaining part of the wick and the carrier may be thrown away and a new wick and carrier inserted into the old sleeve.

From the foregoing description of a preferred form of my invention, it will be seen that I have provided a simple wick carrying mechanism, which can easily be adjusted and in which nearly all of the wick is used. It will also be seen that with my invention the same sleeve may be used repeatedly, and that a new sleeve need not be provided with each new wick, as is the present practice. F urthermore, by reason of the fact that the wick carrier and wick carrier sleeve are transversely split, the wick will be held firmly by the spring action of these members, and the members may be stamped out of a flat piece of metal, resulting in very economical m anufacturing methods.

I claim:

1. In combination, a transversely split resilient sleeve, a wick-carrier, having a wick attached thereto, and cooperating means as sociated with said sleeve and wick carrier for adjustably securing said wick-carrier and wick within the sleeve.

2. In combination, a perforated cylindrical sleeve, a wick carrier comprising a split resilient ring adapted to have a wick attached thereto, and projections on said carrier adapted to engage the perforations of said sleeve and thereby hold the carrier and wick in position within the sleeve.

3. The combination of a tubular wick, a

' wick carrier comprising a split resilient cyllnder adapted to be located principally within the wick while having at its lower end an up-turned portion to embrace the exterior of the wick, and a perforated sleeve surrounding the wick and carrier.

4. The combination of a tubular wick, a wick carrier adapted to be located principally within the wick while having at its lower end an rip-turned portion to embrace the exterior of the wick, outwardly extending burrs on the Lip-turned portion of the carrier and a perforated sleeve surrounding the wick and carrier, the burrs on the carrier being adapted to cooperate with openings in the perforated sleeve.

5. The combination of a tubular wick, a wick carrier engaging the exterior and interior of the wick adjacent the lower end thereof, a split perforated sleeve surrounding the wick and carrier, a tongue carried by the perforated sleeve on its exterior extending beyond one edge thereof to coact with a retaining member on the sleeve adjacent the other edge thereof.

6. The combination of a tubular wick, a wick carrier comprising a split resilient cylinder adapted to be located principally within the wick while having at its lower end an up-turned portion to embrace the exterior of the wick, outwardly extending burrs on the up-turned portion of the carrier, and a split perforated sleeve surrounding the wick and carrier, the burrs on the carrier being adapted to cooperate with openings in the perforated sleeve, a tongue carried by the perforated sleeve on its exterior extending beyond one edge thereof to coact with a channel on the sleeve adjacent the other edge.

7 In combination, a perforated sleeve having inward projections, a wick carrier having a tubular wick attached thereto and located within the sleeve, the projections cooperating with the wick to hold it in position.

8. In combination, a perforated cylindrical sleeve having inwardly projecting burrs formed by the punching of the holes, a wick carrier having a tubular wick attached thereto and located within the sleeve, the burrs cooperating with the wick to hold it in position.

9. In combination, a tubular wick, a perforated sleeve on the exterior of the wick, a wick carrier having a cylindrical sleeve on the interior of the wick, one of said sleeves having adjacent its edge a tongue projecting across the other edge of the sleeve and the sleeve adjacent the other edge having an 011- set keeper constituting an integral strap displaced from the body of the sleeve to enable the tongue to be passed between the sleeve proper and keeper.

10. In combination, a tubular wick, a carrier therefor having a sleeve on the interior of the wick, a perforated sleeve on the exterior of the wick, both of said sleeves being split longitudinally and being provided with means to maintain registration adjacent the separation, said means comprising a tongue projecting from one edge of the sleeve overlapping the other portion of the sleeve beyond the separation, and a pair of tongues on such other portion of the sleeve projecting from it on opposite sides of the first mentioned tongue and overlapping that portion of the sleeve carrying the first mentioned tongue.

In testimony whereof, I hereunto aflix my signature.
